Sinx=\frac{opposite}{hypotenuse} =\frac{ \sqrt{2} }{2}
     opposite=\sqrt{2}
     hypotenuse=2

Adjacent^{2}+(\sqrt{2 })^{2 }= 2 ^{2}
<span>Adjacent^{2}+2=4
</span><span>Adjacent^{2}=2 
</span>Adjacent=\sqrt{2}

cosx=\frac{ajc}{hyp}= \frac{ \sqrt{2} }{2}
Tanx=\frac{opp}{adj} =  \frac{ \sqrt{2} }{ \sqrt{2} }

Audrey's father gave her 20 tokens to use at Action
rjkz [21]

Answer:

5 tokens

Step-by-step explanation:

<u><em>She spent 1 out of every 4 tokens,</em></u> meaning there are a couple of sets of 4 that we don't know many they are yet that she kept taking from every set 1 token, so if we do,

(Her total tokens) 20 ÷ 4 = 5.
This means that there's 5 sets, then we take 1 from every set so 1 × 5 = 5, that's it

I don't know if that was quite clear tho you can imagine it in a more virtual than mathematical way if you like,

Now Imagine you have 20 tokens in your hand, and you divide them into 5 sets, each set is a set of 4, you keep 3 in your hand then put 1 on a table, then you do this 5 times you'll end up with 5 tokens on the table and 15 in your hand.

<em>You can try that yourself if you want it to be more clear.</em>

Take 20 small pieces of paper, sticky notes or coins whatever you like, then divide them into sets of 4, then lastly take only 1 from each set (and by the way you'll notice that dividing each set into a set of 4 will make you automatically end up with 5 sets) now count all the 1's you collected from each set
they should be 5.

State if each triangle is a right triangle: *<br><br>13 in<br>2 in<br>12 in<br>​
olga_2 [115]

Answer:

It would be a obtuse triangle instead

Step-by-step explanation:

By using pythagorean and theorem (a^2 + b^2 = c^2)

So it would be 13^2___2^2 + 12^2

When you square them, you get 169___4 + 144

144 + 4 = 148, which is less than 169

SO it would be 169>148

So no, not a right triangle
